ATSDR's Toxic Substances Web Portal makes it easy for researchers and citizens to find information about toxic chemicals and related health effects. Learn how toxic substances can affect health and how to prevent exposure.

A chemical spill may have contaminated a rural area's water supply with high levels of arsenic.

Both residents and health care providers can rapidly find the answers they need in ATSDR's Toxic Substances Portal.
